The biggest shock of the box-office weekend?

That Ben Affleck went to No.1 with a slightly old movie? That an even-older movie, Hotel Transylvania, moved up to the No. 2 spot?

Among the smallest wide-release debuts ever for Hanks, Cloud Atlas nonetheless posted the largest per-screen average of any film in the Top 10, and bested fellow newcomers Silent Hill: Revelation 3D ($8 million), Fun Size ($4.1 million) and the Gerard Butler surfing movie, Chasing Mavericks ($2.2 million), which didn't even make the Top 10.

Perhaps expectedly, the much-debated Cloud Atlas was graded a C-plus by opening-weekend audiences. (By comparison, Chasing Mavericks was rated a B-plus its few and proud ticket buyers.)
